The Cork-headquartered electronics manufacturing and design firm PCH International has appointed Mike McNamara, a former CEO of design giant Flex, as its new chairman.
It is understood that McNamara has also invested in PCH, but a spokeswoman for the company said it did not comment on the ownership structure.
The two firms would have been considered rivals in some sectors, and PCH founder Liam Casey said they had known each other for a long time.
Casey said: "Mike has a great passion for operations strategy and supply chain execution. He shares our vision of enabling both global brands and innovative startups to bring new products to market efficiently and sustainably."
McNamara added: "I've admired Liam for a long time, and his ability to stay ahead of manufacturing, technology and business trends."
McNamara was CEO of Flex for 13 years, leading 200,000 employees. It achieved more than $25bn (€23bn) in revenue, and made an $11bn acquisition on his watch.
He retired last year after 25 years with the firm. He is currently a partner at Eclipse Ventures and serves on the board of Workday.
Last year, PCH is understood to have raised $28m in equity.
Its Irish company is unlimited, meaning it does not file detailed accounts. The firm is believed to be growing again, after a restructuring following the loss of a contract with Apple several years ago.
